GeForce GTX 650 Ti 2GB vs Radeon R7 240

Intro

Compare those specifications to the Radeon R7 240, which comes with core speeds of 730 MHz on the GPU, and 900 MHz on the 2048 MB of DDR3 RAM. It features 320 SPUs along with 20 Texture Address Units and 8 Rasterization Operator Units.

Radeon R7 240		28800 MB/sec
	Difference: 57600 (200%)

Texel Rate

The GeForce GTX 650 Ti 2GB is quite a bit (about 307%) more effective at AF than the Radeon R7 240. (explain)

GeForce GTX 650 Ti 2GB		59392 Mtexels/sec
Radeon R7 240		14600 Mtexels/sec
	Difference: 44792 (307%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 650 Ti 2GB is a better choice, by far. (explain)

GeForce GTX 650 Ti 2GB		14848 Mpixels/sec
Radeon R7 240		5840 Mpixels/sec
	Difference: 9008 (154%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of information (counted in megabytes per second) that can be transferred across the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory speed. If the card has DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
